Hirschmann SPIDER 3TX-TAP 943899001|Industrial Ethernet TAP|Network Monitoring Port|DIN Rail
Hirschmann SPIDER 3TX-TAP Industrial Ethernet Test Access Point
(Article No.: 943899001)
Hirschmann SPIDER 3TX-TAP 943899001 | Industrial Ethernet TAP | Network Monitoring Port | DIN Rail
The Hirschmann SPIDER 3TX-TAP (943899001) is a specialized industrial network monitoring device designed for non-intrusive, permanent access to network traffic in critical infrastructure environments. This Test Access Point (TAP) provides complete visibility into network communications between two devices without affecting network performance or creating a single point of failure.
Key Features and Product Highlights
-
Passive Network Monitoring: Provides full-duplex, non-intrusive access to 100% of network traffic between two connected devices, including error packets and normal data transmission
-
Fail-Safe Operation: Integrated fail-safe relay ensures continuous network connectivity between Port A and Port B even during power loss or device failure, eliminating network downtime
-
Three-Port Architecture:
-
Port A & Port B: In-line network connections for transparent installation between two network devices
-
Monitor Port: Dedicated output for connecting network analysis, security monitoring, or diagnostic equipment
-
-
Zero-Configuration Operation: True plug-and-play functionality requires no IP address, software configuration, or management overhead
-
Rugged Industrial Design: IP30-rated metal housing with extended operating temperature range (-40°C to +75°C) suitable for harsh industrial environments
-
Complete Traffic Visibility: Captures all network traffic at wire speed, providing more comprehensive monitoring than switch port mirroring (SPAN) capabilities
